l Application tiled November 2'3, lB9$y3. Serial No. 737,982. (No model.)

To all. roh/m it may concern:

Be it known that I, WILLIAM lvLBAnNns, a citizen of the United States, residing atPhiladelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Ironing Machines, of which the following is afull; clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to ironing-machines, and has for its object to produce a machine wherein the ironing or finishing roller will travel ina straight line above a fiat table, wherein the direction of travel of the roller may be reversed instantly without shifting the driving-belt, wherein the roller will Vbe reversed automatically when it reaches the end of its travel in one direction and be brought to a stop automatically when it reaches the end of its travel in the opposite direction, and wherein the general construction and opera- Y tion of the machine will be improved.

The invention consists in improved means for actuating the roller in a horizontal plane overa flat horizontally-disposed table, in improved means for manually and automatically controlling the direction of tra'vel of the roller, in improved spring-bearings forthe table, in improved mechanism for positively rotating the roller, and in various details of construction, all of which will be hereinafter described;

In the drawings, Figure 1 is a plan view. Fig. 2 is aside elevation. Fig. 3 isa rear end view. Figs. 4 and 5 are sections on lines44 and 5 5 of Fig. 1.

A is the frame.

B is a screw-shaft journaled in the bearings b and b, the latter bearing, at the rear of the machine, being a movable .one and will be hereinafter more fully described.

C is a nut on the screw B.

- Dis a cross-head having a loose bearing for the nut C and extending toward and beyond each side'of the machine. A carriage E is secured near the outer ends of the cross-head, which carriage has rollers e on tracks or guides F on the frame. At the outer ends of the cross-head are brackets G', supporting bearingsfortheironing-rollerGr. Dependent upon the direction of rotation of the screw, the ironing-or finishing roller and its supporting frame, comprising parts D E e GQ, will travel either forward or backward.

H is asheave, one at each end of the roller G.

IIis a cable one end of which is secured to a lug 71l on the front of the frame, while the other end` is secured to a hooked tension-adj listing screw h2, extending through a lug h on the rear of the frame. A cable extends around each sheave, and thus by causing the roller to travel back and forth a positive movement of rotation is imparted to the finishingroller. If desired, the finishing-roller may be rotated by friction alone.

I is the linishing-table-supporting frame, and I/ the finishing-table supported thereupon. The tableframe is triangular in shape, the two rear corners being connected, through bolts j, with lugs j on the frame, while coinpression-springs surround the bolt between the frame and the lugsi The bolts are also provided with nuts ji for adjusting the height of the frame. The front corner of the tableframe is connected, through a bolt jg, with a lugj4 on the frame,'there being nuts 3'5 for adjusting theheight of the frame and a nutj6 for adjusting independently a compressionspring jm, which surrounds the bolt above the lug j4. the table vertically toward or away from the finishing-roller and for adjusting the springpressure of the table. i

I provide the following means for directly rotating the screw B in either direction: At the rear end of the screw-shaft is a beveled friction-gear K, and on the driving-shaft 7c are the beveled friction-gears K and K2. The driving-shaft rotates in bearings at the rear of the machine and has the driving-pulley K3 and idle pulley K4. The shaft 7o constantly revolves in one direction. If the rear end of the screw-shaft is moved sidewise to throw friction-gear K in contact with friction-gear K', the screw-shaft is rotated in the direction to carry the roller-frame forwardly, while if the shaft is moved tothrow friction-gear K in contact with .friction-gear K2 the shaft is rotated in the other direction to carry the roller-frame rearwardly.

I provide the following means for manually controlling the direction of rotation of the screw-shaft and the consequent direction of `travel of the finishing-roller:

Thus means are provided for moving IOO L is a lever pivoted between its ends to the cross-bar Z. Secured to its upper end is the movable bearing b.

L is a link connecting lower end of lever L with bell-crank L2, pivoted on the frame of the machine;

L3 is a link connecting bell-crank L2 with lever L4, secured to the controlling-shaft m. Secured to the shaft m are the treadle M and weighted lever M. If the foot-treadle is depressed, the link L3 is drawn forward and the link L moved to throw the screw-shaft in the opposite direction and engaging fric tion-gears K and K', causing the screw to rotate in the direction to carry the finishing-roller frame toward the front. As soon as the pressure on foot-treadle is released the weighted lever acts to throw the screw-shaft to the other side, engaging friction-gears K and K2 and causing the travel of the finishing-roller frame to be reversed. It will be understood from this description that so long as the operator maintains the foot-treadle depressed the finishingroller will move forwardly. At any time that he releases the foot-treadle the weight will through the mechanism described cause the finishing-roller to move backwardly. If the operator neglects to release the foot-treadle, I provide the following means for automatically reversing the travel of the finishing-roller frame when it reaches its desired forward limit of travel: v

N is a lever pivoted between its ends to a lug n on the machine-frame. The lower end of the lever is secured to the link L3, while the free upper end is in line of travel of the yoke D. When in the forward movement of the nishing-roller frame (friction-gears K and K being in gear, as described) the crosshead D strikes the lever N, the link L3 is thrown backward, raising the treadle, on t-he one hand, (although the operators foot may be upon it,) and, on the other hand, throwing the screw-shaft to the other side, engaging gears K and K2 and immediately reversing the rotation of the screw and the direction of travel of the finishing-roller frame. The finishing-roller frame is automatically brought to a stop in its travel toward the rear of the machine in case it should not be manually reversed by the depression of the foot-treadle before reaching its extreme limit of travel by the following mechanism:

O is a pin on the cross-head.

P is a projection on the cross-bar Z of the frame, and P is a projection on the bearing b', the side of projection P being in exact alinement with the side of pin O. When the finishing-roller frame is traveling backward, friction-gears K and K2 are in engagement, as before described, and the space between the bases of the projections P and P is slightly less than the width of the end of pin O, the difference being equal to half the eX- treme side motion of the movable bearing for the screw-shaft. When, therefore, the rollerframe has traveled back far enough to cause pin O to enter between the projections, the projection P will be forced to one side, moving the screw-shaft sufficiently to disengage the friction-gears K and K2, but not sufficiently to engage friction-gear K with friction-gear K. When it is desired to start the rollerframe forward, the foot-treadle is depressed sufficiently to engage friction-gears K and K', as before described.

It will be understood that the sheave H may be of any desired size, and sheaves of different diameters are readily interchangeable to vary the speed of rotation of the roller. By varying the speed of rotation of the roller relatively to the speed of longitudinal travel of the roller I produce the finish desired. Itv

will be understood that the roller may be heated in any desired manner.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-
